2 Claims.

This invention relates to an improved dynamite box.

One object ofthe invention is to provide a dynamite'box fabricatedcompletely of wood so that no electric current carrying material of anydescription will be embodied in its construction.

which are located in opposed relation. In forming the box, the bottom isshiftedinto position with the elements Ii and I in their respectives1o'ts'8 and 9. Transversely extending grooves 6a and 1a are formed inthe bottom wall 5.

Near the corresponding upper end portions of the walls I and 2, butbeneaththe rounded por- And a still further object of the invention isto provide a box of this character which will be of simple constructionand which will be highly eflicient in use.

Other objects of the invention, not specifically mentioned in theforegoing, willbecome apparent during the course of the followingdescription.

In the accompanying drawing forming a part of my application.

Fi ure 1 is a perspective view of my improved dynamite box.

Figure 2 is a. vertical sectional view on the line 2-2 of Figure 1,looking in the direction indicated by the arrows.

Figure 3 is a vertical sectional view-on the line 33 of Figure 2. I

Figure 4 is a top plan view of the device, the handle employed beingpartly broken away in order better to show the position of thetensioning means when the latch employed is in operative position forholding the front closure in closed position.

Referring now to the drawing, throughout the views of which likenumerals of reference will be seen to designate like parts, the numeralsI and 2 indicate the side walls of my improved dynamite box. These sidewalls, as well as all the other parts of the box, are formed of woodor.'

other non-metallic material. The'walls I and 2 are formed with straightcorresponding lower end portions 3 and extended rounded upper end tions4 thereof, is positioned the top wall III of my improved box. The topwall is of gneater thickness than the bottom wall 5 and is formed withconnecting elements II and I2 which, like the elements 6 and I, are ofdove-tail formation. The elements. II and I2 are slidable in slots I3and I4 which are shaped to receive said elements and are located inopposed relation to the walls I and 2.

Formed in the top wall III, substantially medially of its width andextending the major portion of its depth, is a dove-tail shaped guideslot I5. The guide slot communicates with the forward edge of the wallIII and slidably receives a guide .element I6 which is formed on theunder side of a latch member I1, said latch member being ofsubstantially rectangular shape in cross section and being of a lengthsubstantially the same as the depth of the complete dynamite box. Aswill be seen by referring to Figure 2, the guide element I6 terminatesshort of the forward end of the latch member I! a distance equal to thethickness of the front closure I8 presently to be described in moredetail.

In order normally to urge the latch member I1 forwardly, I provide arubber band I9. By referring to Figures 1 and 4 of the drawing, it willbe seen that the band I9 is stretched so that portions thereof arefitted in slots 20 formed in the front edge of the top wall I0 near theends thereof. The band I9 is stretched rearwardly in straddling relationto the latch member I1 and has a rear portion engaged in an inclinedkerf or notch 2|. It will now be understood that the band I9 willnormally urge the latch member I! forwardly so that the front end faceof the element I6 will engage the upper inner margin of the frontclosure I8. In this position, the forward end of the latch member willoven-hang the upper edge of the front closure I8 for effectively holdingsaid front closure in closed position.

The front closure I8 is formed with guides 22 and 23 which are slidablein vertically extending tracks 24 and 25 formed in the walls I and 2near their corresponding forward edges. Formed in the front face of theclosure I8 is a finger hold 26 which will permit convenient raising ofthe closure for exposing the interior of the box,

when the latch member I! is retracted, for freeing the forward endthereof from the upper edge of said front closure IS. A tongue l8a isformed on the lower end'of the front closure l8 and is engageable in thegroove 6a, formed in the bottom all 5, when said front closure is inclosed position.

My improved dynamite box is provided with a I rear wall 21 which is heldin place at its upper end by means of wooden dowels or pins 28 whichextend through the rear margin of the top wall.

Under no circumstances will nails or other metal fastening devices beemployed. Any suitable number of the dowels or pins 28 may be used.

- The upper end of the rear wall is reinforced by engagement with ashoulder Illa on the lower rear edge of the top wall l0. As shown inFigure 2, the rear wall 21 is formed at its lower end with a tongue 21awhich engages in the groove 1a in the bottom wall 5. As will be seen inFigure 4, the rear wall 21 is formed with guides 28a which are slidablyengageable in grooves 28b which extend along the side walls for adistance equal to the height of 'the rear wall. It will now be seen thatthe rear wall will be eifectively held in place without the use ofmetallic fastenings of any kind.

In order to permit convenient handling of my improved dynamite box, Iemploy a handle 29 which extends between the side walls I and 2 at thecurved upper ends 4 thereof.

Attention is directed to the fact that inasmuch as the guide'slot I5 isof a shape to closely conform to theshape of the guide element 16,upward displacement of the latch member from the wall III will beprevented.

Havingthus described the invention, what is I claimed is: I

1. In a dynamite box having a top wall and a front closure, said topwall having a guide slot of dove-tail shape, said top wall having slotslocated near the ends of its forward edge, a latch member carried by thetop wall and having a guide element of dove-tail formation slidable inthe guide slot, said guide elementterminating short of the'forward endof the guide slot, and aresilient band carried in the slots in the topwall and engageable with the latch member for normally urging the latchmember forwardly so that the forward end of the guide element willconfront the upper inner margin of the front closure and the forward endof the latch member. will overhang the upper edge'of said front closurefor preventing upward displacement of the front closure, said dove-tailshaped. guide slot cooperating with the dove-tail shaped element forpreventing upward displacement of the latch member from the top wall.

2. A dynamite box having a top wall formed with a slot, a front closurefor the box, a latch member having a guide element slidable in the slot,said latch member having a notch and said top wall having spaced slots,and a resilient band extending between the top wall and the latch memberand being engaged in the notch andthe slots and normally urging thelatch member into a position with its forward end portion overhangingthe front closure and latching said front closure in place.

JOHN v. HAMMOND.
